Subject: gpu-compute: init valid field of GpuTlbEntry in default ctor
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a0d4019abda8b39285deaf2f8f262b7682ece4de;p=gem5.git

gpu-compute: init valid field of GpuTlbEntry in default ctor

valid field for GpuTlbEntry is not set in the default ctor, which can
lead to strange behavior, and is also flagged by UBSAN.
